Via its "error" attribute, you can fake the result of verify(), thereby
you can test many of TSIG related tests without requiring actual crypto
setups. "error" should be either a TSIGError type value or a callable
object (typically a function). In the latter case, the callable object
will take the context as a parameter, and is expected to return a
TSIGError object.
